 | | | DNS lookup failure on Linksys router | DNS lookup failure on Linksys router 2004-12-19 - By Joshua E Vines

This is a SOHO network. ISP is Verizon. Two computers running WinXP,
three running Win98. Router is 192.168.1.1 and has no name or domain. No
domain has been asigned to this network by Verizon (dynamic IP address).
For the sake of arguing, three computers on the network have the names:
phoenix1 (WinXP), phoenix2 (Win98), and phoenixl (Shrike).
Router serves as DNS for Windows (only one DNS entry set on the Windows
machines).
'hosts' contains:
127.0.0.1 localhost.localdomain localhost lo
192.168.1.1 router
192.168.1.105 phoenixl #as assigned by the router's DHCP
#(low DHCP traffic so it does not change)
Except for localhost, hosts on the Windows machines are blank.
When phoenixl is not listed, hostname [-s|-a|-i|-f|-d|-y] (any of the
options will do it) reports "Host name lookup failure". hostname without
any options reports "phoenixl". On startup, X-Windows (not to be
confused with Windows XP), complains of name resolution problems.
When phoenixl is listed, hostname [-s|-a|-i|-f|-d|-y], reports
"phoenixl" like it should.
In either case, nslookup [/anyhostname/] reports ";; connection timed
out; no servers could be reached".
'resolv.conf' contains:
nameserver 192.168.1.1
'ifcfg-eth0' contains:
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
USERCTL=no
PEERDNS=no
TYPE=Ethernet
DHCP_HOSTNAME=phoenixl
ifconfig -a reports:

phoenix1 and phoenix2 can ping phoenixl by name.
phoenixl can not ping phoenix1 and phoenix2 by name.
p.s.: do you know of a command or an otherwise short program to convert
end-of-line characters (to go from Linux to DOS and back) in text files?
